Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644722, here are decompositions:

19 + 8644703 = 8644722
43 + 8644679 = 8644722
61 + 8644661 = 8644722
71 + 8644651 = 8644722
89 + 8644633 = 8644722
113 + 8644609 = 8644722
193 + 8644529 = 8644722
211 + 8644511 = 8644722

Showing the first eight; more decompositions exist.
